Abstract
A condenser microphone and a method for discriminates a first segment and a second segment in a spoken sound, is provided by using carbon nanotube bundles as capacitor materials. Such capacitor capacitance varies due to the quantum thermal mechanism of CNTs when a spoken sound containing vowel segments and consonant segments passes through the CNTs, so that the vowel segments and the consonant segments can be detected and separated.
Claims20
A microphone that discriminates a first segment and a second segment in a spoken sound, comprising:
- a set of carbon nanotube bundles, the spoken sound passing through the set of carbon nanotube bundles;
- and
- an electrode block, the electrode block including a set of conducting plates and an electrode electrically connected to the set of conducting plates;
- wherein a carbon nanotube bundle of the set of carbon nanotube bundles is located adjacent to the electrode block.
A method for discriminates a first segment and a second segment in a spoken sound, comprising:
- passing a spoken sound through a set of carbon nanotube bundles;
- connecting an electrode in an electrode block electrically to a set of conducting plates in the electrode block;
- and
- locating a carbon nanotube bundle of the set of carbon nanotube bundles adjacent to the electrode block.
